The bounding discontinuities used to delineate the Sparky Allomember correspond to marine flooding surfaces (FS). Based on the integration of ichnological and sedimentological characteristics of succession, ten discrete facies have been identified. These are combined into five recurring facies associations.Facies Association 1 (FA1) comprises sediments deposited below fairweather wave base but above storm wave base. Facies associations 2 and 3 (FA2 and FA3) coarsen upward and represent the progradation of wave- and storm-dominated shorefaces as well as mixed river- and wave-influenced deltas, respectively. Facies Association 4 (FA4) typically cuts through FA3, and displays a fining-upward trend, and is interpreted as distributary channel deposits. Complete cycles of FA2 and FA3, wherein the tops of the cycles have not been removed by downcutting channels, are capped by coastal plain/delta plain deposits of Facies Association 5 (FA5). The Sparky Alloformation terminates at an upper contact marked by renewed marine transgression and the formation of a regionally extensive transgressive surface of erosion (TSE).Three coarsening-upward cycles are identified within the Sparky Alloformation, each bounded by allogenically produced flooding surfaces. These units, termed Lower, Middle and Upper allomembers, are characterized by wave-and storm-dominated shorefaces and associated mixed river-and wave-influenced deltaic successions reflecting progradation towards the N-NW. The Sparky Alloformation consists of sediments deposited during periods of pronounced progradation and corresponds to a highstand systems tract. You do not currently have access to this article.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
